Question

The output Y of the gate circuit shown in the fig is

• A. $\overline{A}+\overline{B}$
• B. $\overline{\overline{A}+\overline{B}}$
• C. $\overline{A+B}$
• D. A + B

Answer 1

The correct option is C $\overline{A+B}$

Here, OR gate is followed by NOT gate hence, the addition of inputs will be reversed in output i.e. $Y=\overline{A+B}$
